Good morning , Mr Croft .   Good morning , nurse . I want to see the dentist , please .   Do you have an appointment ?   No , I don't .   Is it urgent ?   Yes , it is . It's very urgent . I feel awful . I have a terrible toothache .   Can you come at 10 am on Monday , April 24th ?   I must see the dentist now , nurse .   The dentist is very busy at the moment . Can you come at 2 PM ?   That's very late . Can the dentist see me now ?   I'm afraid that he can't , Mr Croft . Can't you wait till this afternoon ?   I can wait , but my toothache can't !
